Knowledge ( Q&A )

Metalworking is the process of working with metals to create individual parts, assemblies, etc. To prevent burning and smoking, metalworking fluid (MWF) is the most important role which is the name given to a range of oils and other liquids. During machining, MWF is used to reduce heat and friction, and to remove metal particles, to cool and lubricate metal work-piece.

The oils, coolants and lubricants used in metalworking shops are often overlooked as an opportunity to improve process efficiencies. However, the standard machining or grinding shop sees the lubricant and coolant as the least important factor in the total cost of machining and the last place to look for process improvements. Metalworking fluids work well, until they don’t. And when they go wrong, it can be a show stopper.
